n recognition and mourning of the victims in newtown, connecticut. and now the context, jon, that you were talking about. there is no way to compare one heart-breaking tragedy to another. we know that. and any other way that we would do it is maybe look at the place in history. hard to concede that something could have happened worse than this scene. from april of 2007. a student killed 32 fellow students and faculty, at virginia polytechnic and state university in blacksburg, virginia. it is still the worst single act of gun violence in u.s. history. an the only school shooting that involved more fatalities than today. for so many of us today was a reminder of one day on april 20, 1999, when the now infamous names kle became part f the american dialogue. we suffered great heartache as the two students opened fire and killed 12 other students about teacher and wounded 20 others before killing themselves at columbine high school. looking further back to history now, really the first time the nation dealt with this kind of violence on a campus. august
